ChibiOS Free Embedded RTOS

Hello again Giovanni!

I checked, debugged etc. my code.

USB_REQ_GET_DESCRIPTOR requests USB_DESCRIPTOR_DEVICE_QUALIFIER; I added handling for that.

The following is from default_handler (hal_usb.c):


.
.
case (uint32_t)USB_RTYPE_RECIPIENT_DEVICE | ((uint32_t)USB_REQ_GET_DESCRIPTOR ...

Is it possible your descriptor is wrong somehow? it happens after the host retrieves it.

Giovanni

Do you mean especially (USB) device descriptor or configuration one or what?

Hello again Giovanni!

As I mentioned in the previous mail


I noticed that bool requestsHook(USBDriver *usbp) receives

* USB_REQ_SET_ADDRESS
* USB_REQ_SET_CONFIGURATION
* USB_REQ_GET_DESCRIPTOR


were the only messages what I catched by debugging; I did not see any my own USB messages in bool ...

Hello again!

I want tell more about this stall error.

I have a ChibiOS based system which applies my own defined messages. I apply bulk transfer in my system. My system is capable to handle (receive and transmit) the first my own defined USB message but second one fails because of the stall error ...

Hello Giovanni!

I made the following changes (the following is from ChibiOS 21.11.2 free /os/rt/include/chrestrictions.h, lines 57 - 61):


/* System tick limited to 1000hz.*/
#if CH_CFG_ST_FREQUENCY > 1000
// #undef CH_CFG_ST_FREQUENCY
// define CH_CFG_ST_FREQUENCY 1000
#endif

Hello again!

Yes, I downloaded ChibiOS 21.11.2 free . Unfortunately I met the same kind of problems (my application did not start etc.) with ChibiOS 21.11.2 free what I met with ChibiOS 21.11.1 free .

ChibiOS 21.11.2 free generated the following:


text data bss dec hex
13348 0 131072 144420 ...

Hi,

So it is:

CH_CFG_ST_FREQUENCY set to 1000 that prevents your application from working. Is there anything in your application that requires 10000? Post your mcuconf.h, it could be that 1000 cannot be obtained because your other settings.

Anyway, I will make CH_CFG_ST_FREQUENCY unconstrained ...

Hello again Giovanni!

My parameters&values are
#define CH_CFG_ST_FREQUENCY 10000
#define CH_DBG_STATISTICS FALSE
#define CH_DBG_TRACE_MASK CH_DBG_TRACE_MASK_ALL

Chibios versions 21.11.1 and 21.11.2 started (with my parameters&values) but 21.11.1 free did not.

I tried the following parameters ...

Hello again Giovanni!

I tried the following parameters&values but no success:


#define CH_CFG_ST_FREQUENCY 1000
#define CH_DBG_STATISTICS FALSE
#define CH_DBG_TRACE_MASK CH_DBG_TRACE_MASK_DISABLED


Do you have a version 21.11.2 free somewhere?

Best regards

Hello folks!

Are there differences between ChibiOS 21.11.1 and ChibiOS 21.11.1 free versions?

The settings&configs were exactly the same for the previous ones but data size was 0 for ChibiOS 21.11.1 free .

ChibiOS 21.11.1 free based application did not start, a lsusb command did not see USB addr ...
